I've made a drawing app based on my physical sketching practice, using fluid sim and some shader tricks to mimic watercolor-style ink washes. Best used on iPad or with a drawing tablet. The linked article shows how the core engine works, with plenty of little interactive demos. It was fun to make, sharing in hopes others find it fun too :)

The story of AI for the last three years has been written in megawatts. Nvidia GPUs stacked in desert data centers . Models with trillion-parameter counts. APIs that pipe your prompts, photos, and personal data to the cloud, burn a forest of electricity to process them, and return an answer 800ms later. If you're building with AI in 2026, the default assumption is that intelligence lives somewhere else. Your device is just a glass terminal. Apple has been telling a different story. No press tour. No "AGI in your pocket" hype cycles. Instead, a decade of silicon releases where the Neural Engine number (FLOPS) quietly doubled, then doubled again. Core ML updates that casually added transformer support. Here is my thesis : Apple’s on-device AI strategy is a privacy-first, performance-oriented architectural break from cloud-centric AI. By co-designing silicon, models, and APIs to run locally, Apple is unlocking a new class of local-first applications where user data never leaves the device, latency is measured in milliseconds, and features work in airplane mode. This doesn’t kill cloud AI. But it forces every developer to answer a new question: what part of your product must be in the cloud, and what gets better when it stays in the user’s pocket? This post is a technical teardown of that shift. I’ll cover the hardware realities of the Neural Engine and unified memory, the brutal constraints of fitting LLMs on device, what Core ML actually gives developers in 2026, and where this architecture creates new product opportunities that cloud-first can’t touch. I’ll also be blunt about the limits. On-device AI won't replace GPT-5 training clusters. But it might replace 80% of the API calls you make to them. At this moment, cloud AI gets all the headlines, but the real transformation may already be running 24/7 in your pocket, without ever touching the internet. Why the On-Device Push? Apple's AI strategy looks slow only if you measure it in keynote superlatives. Measure it in

Introduction Zhipu AI (THUDM) has officially released GLM 5.2 , the latest iteration of its flagship open-weights model family. Announced today by Jie Tang on Twitter, the release is already making waves on Hacker News — racking up 269 points and 146 comments within hours. For developers who have been watching the open-weight LLM race, this is a significant moment. What's New in GLM 5.2 GLM 5.2 builds on the GLM-4 series that put Zhipu on the global map. The release focuses on three areas that matter most to production teams: Stronger reasoning and coding : Improved performance on multi-step reasoning benchmarks and competitive code generation against closed-source models like GPT-5 and Claude 4.5. Better multilingual behavior : GLM has always been strong in Chinese; 5.2 pushes English-quality code reasoning and longer-context retrieval closer to frontier levels. Longer context window : Reports point to a 200K+ token context with reduced degradation on long-document tasks — useful for codebase-level analysis. Weights, inference code, and a technical report have landed on Hugging Face under the THUDM organization, with an OpenAI-compatible API endpoint exposed by Zhipu's own platform. Why It Matters The open-weights race has consolidated around a handful of serious contenders — Llama, Qwen, DeepSeek, Mistral, and now GLM. Zhipu's positioning is unique: a Chinese lab that consistently weights-and-releases frontier-class models while still maintaining a hosted commercial API. For developers, that translates to real options: You can self-host on a single H200 or a pair of RTX 5090s and skip per-token API costs entirely. You can route between self-hosted GLM 5.2 and a hosted Anthropic/OpenAI endpoint depending on cost, latency, and capability. You get an OpenAI-compatible endpoint, so dropping GLM into an existing stack is a config change, not a rewrite. The Bigger Picture GLM 5.2 lands on the same week that U.S. regulators have reportedly cracked down on Anthropic model
